started to add static (fixed if) statement based decision rules based on gigE numbers
added mca params so that a user can force a certain algorithm/segment/topo on a per collective basis
(this is not in the fixed call path but only in the dynamic (at com create) call path).
(these params can be used by test suites such as OCC to choice which algorithm they are using).

Note, we are failing the ring tests in the intel p2p test suite, but we seem
to fail the same tests under the current trunk.. will look into this further.

convertor (when prepared) increase the reference count on the used datatype. This reference count
will be released only when the OBJ_DESTRUCT is called on a convertor. However, having to call
OBJ_CONSTRUCT and OBJ_DESTRUCT on each request every time we want to use it (even when it come
from the cache) is an expensive operation. This can be avoided is the OBJ_DESTRUCT will leave the
convertor in exactly the same state as OBJ_CONSTRUCT. With this approach we just have to call
OBJ_CONSTRUCT for each convertor once when we initially create the request.

memory initialization, call opal_progress() to push any pending events
around and possibly yield the processor if nothing entertaining is happening.
This should probably go to the 1.0 branch.

--with-devel-headers is given to configure:
* allocator, rcache, and mpool were putting things in the wrong place
* timer wasn't installing the inline implementations at all

number of collective operations and simplifies the logic significantly.
- introducing a special case if size of comm == 1, avoiding thus collective
operations as well ( i.e. no need for hierarchies)
- fix for an unsymmetric case. Still to be tested.

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

First cut on barrier (which from my perspective does not make sense from the
performance point of view) and on allreduce (which might make sense),

done. This version also doesn't break ompi (at least if its not chosen :-) ).
New features compared to the version from last Thursday (where bcast and
reduce seemed to work in most scenarios):
- clearer internal infrastructure
- ability to handle all root processes with a (hopefully) minimal number of
local leader communicators.
This commit was SVN r7769.
(actually a work around for an optimisation in the reduce for not saving ops on the first recv of each segment)
Minor change in topo.
This commit was SVN r7758.
- update the hierarch stuff to use btl's instead of ptl's
- start the new logic regarding how to handle local leader communicators
This commit was SVN r7691.
